Adult Height Predictor
Using the Mid-Parental Height (MPH) formula — the standard clinical method used by paediatricians worldwide. Enter both parents' heights to calculate your child's predicted adult height range.
Height Comparison
📐 How the Formula Works
🧬 What Influences Final Height?
- Genetics (~80%) — the strongest predictor, captured by this formula
- Nutrition — adequate protein, calcium, zinc, and vitamin D are essential during growth years
- Sleep — 80% of growth hormone is released during deep sleep; consistent bedtimes matter
- Physical activity — moderate exercise (especially weight-bearing) supports bone density
- Chronic illness — prolonged illness or malnutrition can affect growth velocity
- Hormones — thyroid, growth hormone, and sex hormone disorders can affect height
🇸🇬 Singapore Average Heights
- Average adult male: ~170–172 cm
- Average adult female: ~159–161 cm
- Singapore Chinese, Malay, and Indian populations have slightly different average heights — this calculator uses generalised population data
- Singaporean children's average height has been increasing each generation with improved nutrition
⚠️ When to See a Paediatrician
- Child is growing less than 5 cm per year after age 3
- Child's height is below the 3rd percentile for age and sex
- Child has stopped growing entirely for >6 months before puberty
- Growth velocity has slowed significantly compared to previous years
- You are concerned about your child's growth for any reason
Current Height Percentile
Enter your child's current age and height to see where they fall on the WHO growth chart. A healthy child can be anywhere from the 3rd to 97th percentile — what matters most is that they're growing consistently along their own curve.

Reference Heights for This Age
📈 Understanding Growth Percentiles
- A child at the 50th percentile is taller than 50% of children their age — this is the average
- Any percentile between 3rd–97th is normal — being at the 10th percentile doesn't mean your child is unhealthy
- What matters most is that your child follows their own growth curve consistently over time
- A drop across 2 major percentile lines (e.g. from 75th to 25th) warrants medical review
- These charts are based on WHO Child Growth Standards
Average Height Milestones by Age
See how children grow from birth to adulthood. Heights shown are 50th percentile (average) based on WHO growth charts, with the typical range in brackets. Enter your child's predicted adult height to see personalised estimates.
🌱 Fastest Growth Periods
- Year 1: Babies grow ~25 cm — the fastest year of life
- Years 1–2: ~12 cm per year
- Years 2–puberty: ~5–6 cm per year (steady)
- Puberty growth spurt (boys): ~8–10 cm/year, typically ages 12–15
- Puberty growth spurt (girls): ~6–9 cm/year, typically ages 10–13
- After puberty: Most girls stop growing at 15–17; boys at 17–19
